Urea transporter

About this Structure
The structure revealed  monomer of the urea transporter in the asymmetric unit.

However, the urea transporter crystallized as a homotrimer that corresponds to its functional biological state, and this is seen when considering the crystallographic three-fold symmetry axis.

To help give a better idea of how the urea transporter is oriented in the membrane lipid bilayer, a slab representative of hydrophobic core of the lipid bilayer as calculated by the Orientations of Proteins in Membranes database(University of Michigan, USA) is shown with the red patch of spheres indicating the boundary of the hydrophobic core closet to the outside of the cell and the dark blue patch of spheres indicating the boundary closest to the inside of the cell.
